1 I Application filed April 1 8, 1914.. Serial No. 832,885., ,1

To all whom it may concern 1 Be it known that L'SAMUEL SWAIN, a citizen of the United States of'Americ-a,iresiding at Grapeville, in the county of Westmoreland and State of Pennsylvania, have invented-certain new and useful Improve ments in Rail-Joints, of which the follow ing is a specification, reference being had therein to the accompanying drawing.

This invention relates to a rail joint. and has for its object to provide a device of such class, in a manner as hereinafter set forth, for connecting the opposing ends of a pair of track rails together without the employv locking pos tion for apurpose to be herein ment of nuts and-bolts, at the same time providing for the necessary contractionand expansion of the track rails due to climatic influences.

Further objects of the invention are to provide a rail joint which is simple in its construction and arrangement, strong, durable, efficient and convenient in its use, readily set up and comparatively inexpensive to manufacture.

With the foregoing and other objects in view the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In describing the invention in detail, reference is had to the accompanying drawings in which Figure 1 is a side elevation of a rail joint in accordance with this invention; Fig. 2 is a sectional plan; Fig. 3 is a transverse sectional view; Fig. 4 is a side elevation, broken away, of the track rails; Fig. 5 is a perspective view of one of the splice bars.

Referring to the drawings in detail, 6 and 7 denote a pair of track rails and each of which includes a head 8, web 9, and a base 10. The opposing ends of the web 9 of the track rails 67 are each provided with a longitudinally extending T-shaped slot 11, and the stem of one slot is arranged in alinement with the stem of the other slot, thereby providing, when the track rails 6-7 are in position, what may be termed an H-shaped opening.

Arranged at one side of the webs 9 of the track rails 67, is a splice bar 12 which engages the heads 8 and bases 10 of the rails,

and is spaced from the. webs 9. The splice bar 12 is provided with an H-shapedopening 13 which is arranged in alinement with the H-shaped'r opening formed by the T- shaped slots 11 in the-webs 9. Arranged above the opening 13, and on the outer face otally mounted thereon a cam 15, and the outer face of the -splice bar 12 is further pro vided with a pin 16 having pivotally mounted thereon one endof a locking dog 17, which is capable of being" engaged by the cam 15, whereby said dog is maintained in after referred to.

of the splice bar12, is a pin 14, having piv- The reference character 18 denotes a splice 2 bar which is arranged upon the sides of the track rails 6- 7, opposite the sides which are opposed by the splice bar 12, and the said splice bar 18 engages the heads 8 and bases 10 of the track rails 6-7. The inner face of the splice bar 18 has formed integral therewith an H-shaped coupling arm 19, formed with notches 20 which provide seats for a locking member to be presently referredto. The arm 19 extends through the H-shaped opening, formed by the T-shaped slots 11, and furthermore extends through the H-shaped opening 13 in the splice bar12, as well as projecting outwardly from the said splice bar 12.

Mounted in the seats formed by the.

notches 20 in a locking member 21 formed,

of a bar of suitable material and which is provided in its top edge with teeth 22, these latter capable of being engaged by the dog 17, and when the latter is maintained in. locking position by the cam 15, the splice bars 1218 are connected together, and under such conditions the track rails 6-7 are coupled in view of the fact that when the nal movement of the locking member 21 is and cam 15.

What I claim is 1. A rail joint comprising the combination'with a pair of track rails having the arrested through the medium of the dog 17 webs thereof formed with T-shaped slots registering to provide an H-shaped open ing,' of a pair of splice 'barsarrangedat the sides of said rails, one of said splice bars provided with an H-shaped opening, an H-sha'ped coupling arm integral with the other of said splice bar and extending through that splice bar provided with the H-s'haped opening, a wedge-shaped locking member engaging in said coupling arm "exteriorly of that splice bar provided with the *H-shaped opening, and means carried by that splice barf provided with an H-shaped opening and'engaging in said locking member to prevent; longitudinal movement of the locking mem her. 5 v 2. A rail joint comprising the 'combina-f tion with a pair oftrack rai1s=having thei webs thereof formed with T-shaped slots? registering to provide an H-shaped opening,

of a :pairof splice bars arranged at the sides of said rails, oneof said splice bars aprovided with an H-shaped opening and H-shaped v coupling arm integral with the other of said splice bars and extending through that splice bar provided with an H-shaped opening, a wedge-shaped locking member engaging in said coupling arm exteriorly of that splice bar provided with an H-shaped opening,i"mea ns carried by that splice bar pro G.
